Getting the hang of it
Absolutely do not give video with audio. In basically all cases you shouldn't be recording audio outside of your house anyway, just to be sure you're legally compliant. I would give video from any of my cams to cops because I've already satisfied that setting up exterior cams to film my property are legally compliant even if they do happen to inadvertently capture off-property material. My neighbors' yards, for example, are captured on my cams, as is the street. Of course if my cams were focused directly on a neighbor's window that is a no-no.
I disagree, it is better to KNOW the laws for your local then just putting a blanket no audio always policy in place. For example here in Tennessee we have the one party consent rule for audio, in short this allows the recording of audio as long as one person consents to it (and that includes you).
I record the audio on ALL my outside cameras and have provided these recordings to police when asked, and the audio portion has been used by police/prosecuters. In fact the audio on one recording I gave was a significant help in one of the cases.
You should check what is acceptable in your local because if you are allowed to record audio you should - it can be very helpful at times (especially with gun shot sounds).
